Inventor: MIZUHARA KENZO
IPC: E21D23/03
Filed: 1997-04-28
Abstract: PROBLEM TO BE SOLVED: To execute supporting works without dangers by supporting only positions where rocks easily collapse with lattice-shaped lining panels and removing the panels in accordance with the position where rocks do not presumably easily collapse.

Title: Synchronizing method of timer
Inventor: TSURUTA SETSUO
IPC: G06F15/16
Filed: 1984-06-20
Abstract: PURPOSE:To make a timer in a dispersion system coincide with a real time highly accurately by forming a message in which the time of the timer is written, sending the message to a reference node to teach the shift of the timer to the reference node. CONSTITUTION:After completing the processing of an unprocessed message on a network by transmitting an initializing message from the reference node 1 side to all nodes, a transmission control device 24 and a processor 21 in each node are initialized, and after the passage of sufficient time, a transmission control device 14 and a processor 11 on the reference node 1 are initialized. Then, a message 51 in which the current time indicated by the timer 13 is written is formed to await the initializing message from a non-reference node 2. At the arrival of the time-written message 52 from the non-reference node 2, the shift of the timer 13 can be detected from a difference between the written time and a current time indicated by the timer 13.

Title: Ultrasonic doppler blood flow apparatus
Inventor: NAKAMURA YASUHIRO
IPC: A61B8/06
Filed: 1988-05-23
Abstract: PURPOSE:To detect high speed blood flow at relatively low oscillation frequency, by modulating an echo signal obtained by an ultrasonic probe and detecting the Doppler deflection signals of the upper and lower wave bands of the modulated echo signal by a Doppler detection means to calculate the frequency difference between two Doppler signals. CONSTITUTION:A transmitter 1 generates pulse voltage and the ultrasonic vibrator in a probe 2 is excited to output an ultrasonic pulse to a living body. The ultrasonic pulse is reflected from a reflecting body in the living body to become an echo signal which is, in turn, received by the ultrasonic vibrator to be amplified by an amplifier 3. The echo signal obtained by the ultrasonic probe 2 is modulated to be allowed to fall to a low frequency region. The Doppler deflection signal of the upper wave band possessed by the modulated echo signal is detected by a Doppler detection means while the Doppler deflection signal of the lower wave band is detected by the second Doppler detection means. A frequency operation circuit 10 calculates the frequency difference between the Doppler signals outputted from the Doppler detection means to compress Doppler deflection frequency. By this method, high speed blood flow can be detected at low oscillation frequency by a simple constitution.

Title: Production of magnetic recording medium
Inventor: KOGA NAOKI
IPC: G11B5/84
Filed: 1988-05-23
Abstract: PURPOSE:To decrease medium modulation noises and to prevent the degradation in SN by flawing an NiP surface on a substrate in the relative moving direction with a magnetic head to roughen the surface and removing the surface down to a prescribed depth. CONSTITUTION:The NiP film 2 formed on the substrate 1 is flawed along the relative moving direction with the magnetic head to roughen the surface layer and thereafter, the roughened NiP film 2 is removed down to the prescribed thickness from the surface. The parts changed in the material quality, crystal structure, etc., of the surface layer part and the nonuniformly formed oxides, etc., which are the cause to degrade the SN are, therefore, removed by this stage. The ratio of the coercive forces in the direction along the flows put in the NiP film 2 to the coercive force in the direction perpendicular to the direction along the flows put in the NiP film 2 of the magnetic film is thereby approximated to 1 and the degradation in the SN is prevented.

Title: Error detection system
Inventor: NISHIZAKI KOUJI
IPC: H03M13/00
Filed: 1984-06-20
Abstract: PURPOSE:To simplify the constitution of a repeating device by detecting the change point of the output level of a low-pass filter and detecting an error of transmission. CONSTITUTION:A transmission system which uses mB1C codes ORs received data with its delayed data from a one-bit delay circuit 2 exclusively by the 1st exclusive OR circuit 3. The output signal of this 1st exclusive OR circuit 3 and the output signal obtained by inverting the output signal of the 2nd exclusive OR circuit 4 and delaying the result by (m+1) bits are compared with each other by the 2nd exclusive OR circuit. Consequently, its comparison output signal of every (m+1) bits is inverted when a transmission error occurs, so a DC component is extracted through the low-pass filter 7 and its level is discriminated to detect the transmission error.

Abstract: PROBLEM TO BE SOLVED: To provide a display device which can discriminate an input video signal automatically and accurately out of plural video signals very approximate in synchronizing signal frequency when the device is connected to a computer and its video signal is displayed. SOLUTION: A microcomputer 11 measures a horizontal synchronizing signal and a vertical synchronizing signal out of an input signal for a fixed time, calculates a horizontal frequency and a vertical frequency, obtains resolution based on an actually measured value, while analogizes a signal source from a table. A video detecting circuit 15 detects a video start position and a video finish position. The microcomputer 11 subtracts a value of a video start position from a value of a video finish position outputted from the video detecting circuit 15 and calculates horizontal resolution, compares this value with horizontal resolution based on an actually measured value, and adjusts a frequency of an output dot clock of a PLL circuit 14 so as to prevent an error.

Title: Magnetic video recording and reproducing device
Inventor: FURUHATA TAKASHI
IPC: H04N5/7826
Filed: 1982-07-21
Abstract: PURPOSE:To reduce the control pull-in time to ensure the stable tracking control and to improve both functions and performance of a magnetic video recording/ reproducing device, by distinguishing stably and accurately a desired track when the tracking control starts. CONSTITUTION:A control signal Y is inverted to ''L'' from ''H'' at a circuit 42 and synchronously with the fall of a pulse I supplied from a circuit 41. The pulse I is gated with the signal Y to deliver a pulse T. When a track is discriminated by the pulse T, the local pilot signal P1 is immediately produced successively and circularly from the pilot signal equal to that recorded on the track that is scanned at that time point. Thus it is possible to obtain an instantaneous coincidence between the time series of the pilot signal which is reproduced after the track is distinguished and the time series of the local pilot signal. This ensures quick control for subsequent tracks, therefore the pull-in time is reduced.

Title: Power distribution controller for fuel cell automobile
Inventor: IWASAKI YASUKAZU
IPC: B60L11/18
Filed: 1999-05-06
Abstract: PROBLEM TO BE SOLVED: To provide sufficient traveling performance in a starting operation by restricting power required for starting and performing control for increasing power to be distributed to a motor when a kickdown operation by an accelerator pedal is detected during a starting operation of a fuel reforming system. SOLUTION: A controller 33 increases power to be fed to a motor 29 when an accelerator pedal 35 is depressed by a driver. When a total of traveling power for the motor 29 and auxiliary machine power required for starting a fuel reforming system such as a compressor 15, a fuel reformer 1, and a combustor 3 reaches the maximum power supplied from a battery 27, the auxiliary machine power required for starting is restricted to the minimum auxiliary machine power required for preventing the fuel reforming system from stopping according to the degree of accelerator opening. Afterwards, the degree of accelerator opening above it is ignored, and constant power is supplied to the motor 29. This constitution is applicable to the case where traveling power is not sufficient during a warming up time of a fuel cell 21.

Moreover, while the lower end part of a pumping up part 31 being immersed in the liquid stored in the inside of the container main body 10, the pumping up part 31 is extended to an evaporation part 32 exposed to the outer air. Due to the capillarity of the pumping up part 31, the liquid is evaporated to the outside from the upper face of the evaporation part 32. Consequently, regardless of the remaining amount of the liquid, a proper amount of the liquid can be constantly sprayed in atomized state at high diffusion efficiency to the atmosphere.
